Project Summary Founded in 1924, Barton Malow delivers a broad range of construction services, including general contracting and construction management. From planning to closeout, Barton Malow can help advance even the largest and most complex projects more efficiently. Two steel production lines currently under construction for the steelmaker Severstal North America Dearborn (Severstal Dearborn) illustrate Barton Malow’s proactive approach to project delivery. To help manage the projects, Barton Malow uses Building Information Modeling (BIM) software from Autodesk, including Autodesk ® Navisworks ® Manage, Autodesk ® Revit ® Structure, Autodesk ® Revit ® Architecture, and Autodesk ® Revit ® MEP software. Playing a key role from preconstruction to handover to the client, BIM is an integrated process that has helped Barton Malow to: • Visualize, explore, and understand project characteristics before construction • Resolve interferences in advance and prevent additional construction costs • Save time by completing some tasks as much as 88 percent faster • Provide a model-based handover deliverable to the owner that will help minimize startup time and ongoing operational costs The Challenge The Severstal Dearborn construction projects consist of a new pickling line and tandem cold mill in an existing steel manufacturing facility. In addition, a new hot dip coating line provides automakers with high-quality automotive steel. When complete, the combined construction cost of the production lines will exceed US$200 million. Construction on the lines began in 2008, with Barton Malow building only the hot dip coating line. The projects were approximately 20 percent complete when, facing economic challenges common to the steel industry, the client put them on hold. When construction was restarted in 2010, Severstal Dearborn chose Barton Malow to manage all construction for both lines and to self-perform all civil work, equipment setting, and boilermaker work. According to Joe Benvenuto, project manager with Barton Malow, “Restarting the projects led to many challenges.

The ability to bring together multiple file types within Autodesk Navisworks software was a huge advantage on this job. —Chris Horney Project Engineer Barton Malow
Most importantly, the construction model can continue to deliver advantages to the company long after construction is complete. Bill McNab, project manager with Severstal Dearborn explains, “The BIM model and Autodesk Navisworks will give us awaytovisualizecomponentsandequipmentindetail as we maintain the production lines. There’s noquestionthatBIMhashelpedustosavemoneyon construction costs, and we expect it will help with training operators and maintenance personnel in our facility in the future.”
The ResultAs the steel production lines advance toward completion, Barton Malow and Severstal Dearborn see the benefits of BIM touching virtually every aspect of the projects, from preconstruction to handover. Benvenuto notes, “BIM improves and accelerates even the most routine tasks. For instance, we’re able to prepare layouts for concrete pours88percentfaster.Fromthebigstufftoday-to-dayconstruction,BIMsoftwarefromAutodeskhelps keep complex projects on track.”

of the lines and the 35,000 yards of new structural concrete the construction team would install.
“People think of BIM primarily as a design tool,” says Benvenuto. “But BIM gives us the power to explore how we want to build in advance, as well as streamlining our field processes. On the Severstal Dearborn project, Autodesk Revit Structure helped ussetuplayoutcontrols,design-build5,000yardsof concrete duct bank, and clarify some incredibly complicated foundations. The construction team saved time and reduced the risk of rework.”
Eliminating Clashes The use of BIM on the projects extended well beyondtheconcreteworkBartonMalowself-performs.TheBartonMalowteamandtheirsub-contractors modeled the 6,000 drawings that made up the rest of the construction documentation. Eachcontractorutilizeditsownsoftware,withnotallofthecontractorsutilizingAutodeskproducts.Autodesk Navisworks software allowed Barton Malow to aggregate the various model files into a single, integrated project model. Referring to the model as a guide, Barton Malow explored and visualizeditsconstructionplansincollaborationwith the engineers and subcontractors.
“WiththeNavisworksmodel,everyonecanmoreeasilyvisualizetheprojectasawhole,”explainsChris Horney, project engineer for Barton Malow. “Thatcatalyzescollaborationacrosstheprojectteam. Navisworks helps us share ideas about how tooptimizeconstructionsequencing,andmakesiteasier to capture those ideas.”
The Autodesk Navisworks model also proved invaluable for helping resolve coordination issues acrossdisciplines.WithinNavisworkssoftware,theteam performed clash detection tests. A significant number of conflicts were identified. By working with the project engineers, the team resolved clashes.
“Due to the complexity of the production lines, there were a number of clashes between elements suchasequipment,encasedconduit,piping,existing concrete, and structural steel,” explains Horney. “The ability to bring together multiple file types within Autodesk Navisworks software was a huge advantage on this job.”
BIM for Commissioning and HandoverUsing Autodesk® BIM 360™Field,acloud-basedservice, Barton Malow is leveraging BIM in the field for construction, commissioning, and ultimately, handover. BIM 360 Field allows workers on the job site to update construction information on mobile devices. Automated integration between the BIM 360 Field service and Autodesk Navisworks software helps keep the single project model updated. Critical information is then available in NavisworksasaBIM-basedhandoverdeliverabletothe owner. This creates value in ongoing operations as owners can save time by finding key documents for training staff and important data, such as warrantystartdatesfor equipment.
According to Horney, using BIM in the field should proveespeciallyvaluableduringequipmentcommissioning,“Synchronizingthecommissioningprocess with BIM 360 Field and Navisworks can allow us to link accurate install dates, maintenance manuals, and operational information to the project model.We’resavingtimeaswecapturecriticaldataonmaterials,systems,andequipment.”
BIM for OperationsThroughout the project, Severstal Dearborn has reviewed the construction model with extended project stakeholders using Autodesk® Navisworks® Freedomsoftware,afree*visualizationtool.It has helped them keep up with progress and provide feedback.
BIM accelerates construction planning processes by as much as 88 percent.
